It might not be as easy or convenient to install non-free software on Trisquel compared to other distros, and our documentation and community don't support non-free software, but it's your system and Trisquel does not restrict you from installing non-free software if you choose to. > If I remove those software aftwards, would my OS be free again or should > I reinstall the os because some thirdpart applications corrupt it. There are two issues here: freedom and security. If you stop using a non-free program and remove it, and it no longer has any influence on your life, then freedom-wise everything should be fine. However, depending on the program I suppose that it is possible security-wise that it modified your system in some way that persists after removing the program. I don't know enough about security to know whether this is something to worry about with VirtualBox or JavaFX. By the way, Eclipse actually is free software and can be installed easily from Trisquel's repository.
